Standard loan repayment math. 15k at 8% over 5 years: 304/month, 18,250 total, 3,250 interest. Useful for comparing loan offers.

Quick example

With loan amount of 15,000 and interest rate of 8% (plus term of 5), the result is 304.15. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Loan Amount, Interest Rate, and Term. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

What's happening under the hood

Standard amortisation formula. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

Why payoff plans work

Debt feels overwhelming when it's an abstract total. Break it into a payoff date and a monthly figure and the problem becomes finite — you can see the finish line. That visibility is what this tool provides, and for many people it's the difference between dithering and acting.

What this doesn't capture

Real payoff journeys include missed payments, fee changes, balance transfers, and promotional rates that reset. The calculation assumes a steady plan; reality is rarely that clean. Use the figure as the best-case plan against which actual progress gets measured.

Where to go next

This calculation rarely sits alone in a planning exercise. If you're running these numbers, you'll probably also want the loan affordability calculator, the loan true cost calculator, and the car loan calculator — each one answers a different question in the same territory. Treating them as a set rather than in isolation usually produces a more honest picture.
